Specification of Letters Patent.

Patented Nov. 4, 1913.

Application filed April 5, 1812. Serial No. 688,696.

To all whom it may concern:

Be it known that I, J Miss M. TAYLOR, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Container-Forming Machines, of which the following is a specification.

The present invention relates to an improved receptacle or paper container making machine, and particularly to that type 0 machine for forming containing vessels from card board or other fibrous material for dispensing liquids or other substances where a sanitary receptacle is required.

The principal object of the invention is to provide a machine into which suitably shaped blanks of material, preferably sheets of paraffin coated paper or card board, are antomatically fed in succession to an adhesive applying mechanism, then formed into semicylindrical or substantially U-shaped bodies which are passed onto mandrels and folded into hollow cylindrical bodies; then while carried by said mandrels securing a bottom in each body, and finall after the adhesive has fully dried at the e gcs of the container seams, ejecting the completed article from the mandrel.

A further object of the invention is to render automatically the work of forming containers and applying bottoms thereto, and by doing so materially increasing the output of a container making plant and correspondingly reducing the cost of making said containers.

The invention comprises a feed table for receiving the blanks, means for applying an adhesive to one edge of the blank while it is being carried forward by said feed table, mechanism for forming said blanks into semi-cylindrical or substantially U-shaped bodies, means for removing said semi-cylindrical or substantially U=shaped bodies from said formers onto suitable mandrels carried by a rotatable wheel, clamping arms surrounding said mandrels, and devices for closing said arms around said blanks carried by sald mandrels, a bottom applying station, means for rotating said wheel carrying said blanks from the feed table to the bottom applying station, mechanism for applying a bottom to said blanks, and devices at a distant point of travel of said wheels for opening said clamping arms and ejecting said completely formed container from said mandrel.

With the above mentioned and other ob jects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying sheets of drawings, forming a part of this invention, and ointed out in the claims hereto append it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims hereto appended ma be resorted to without departing from t e spirit or sacrificing any of the advantages of the invention.

Extending upwardly from the rear of the base plate 1 and positioned adjacent. the standard 3, is a supporting standard. 8, provided at its upper end with a rec-; shaft 9,, which provides a supporting axis for the center of a wheel 10, which carries on its front face the container forming mandrels,; the wheel being provided on its peripheral edge with suitable gear teeth 11 which intangularly projecting bearing termesh with suitable teeth on a gear 13 which is mounted on a rotatable driven shaft 14. The shaft 14 is intermittently rotated by a suitable roll 15 carried by the 1 drive shaft 4, the roll moving into and out of engagement with the radial slots 16 of the disk 17 secured to the shaft 14, whereby there is given to the said shaft 14 a step by step rotation by the described Geneva gear mechanism, and the same step by step movement is transmitted to the wheel 10 through the gear 13 and teeth 11.

per end of the standard 2 and at its rear by the support 19; the rear edge of the table terminating. adjacent the front end of the hereinafter described forming man-.

drels carried by the Wheel 10.

The blanks from which the articles or containers are to be formed, are placed on the feed table 18 between the outwardly flaring faces of the arms 20 and 20 projecting from the rear .of a reciprocating feed plate 21 mounted to slide in parallel grooves or slots 22 in the top of the feed table 18. A reciprocating movement is imparted to the feed plate 21 through a rack 22 projecting from the under side of the plate, through a suitable slot 23 in the table, the rack intermeshing with a segment 24 mounted on one end of a shaft 25, supported by a bracket 26 to the underside of the feed table. 'The other end of the shaft 25 is provided with a pinion 27 which intermeshes with a rack 28 projecting from the up er surface of a yoke 29 straddling the drive shaft 4, the yoke being provided with a cam wheel 30 which fits in a cam groove 31 formed in the face of a wheel 32, keyed to rotate with the shaft 4.

As the blank is fed forwardly by the with a thin film of adhesive by any suitable gear 6 mount-. ed on a power shaft 7, adapted to be op-- I 1 clamp arm 36. The shaft 33 is provided exadhesive applying mechanism, preferably comprising an adhesive applying spiral 32 supported by a suitable shaft 33 and projecting through an opening 34 in the feed table 18, the ends of the shaft being jour: naled in bearings in either side of an adhesive receptacle 35 detachably secured to the underside of the feed table as by a teriorly of the adhesive receptacle with a through a suitable opening in the feed table 18, the gear 37 intermeshing with a rack 38 carried by the underside of the arm 21 near the outer edge thereof.

From the above construct-ion it will be observed that as the late 21 with the blank between the arms t ereof is forced rearwardly'the rack 38 will rotate the adhesive applying spiral and the spiral is timed to operate and so constructed as to present a freshly coated edge thereof to the edge of the blank as it is advanced toward the former.

The blank is fed forward to a point adjacent the rear edge of the feed plate 18 and lies directly under a hollow cylindrical former 39 supported slightly above the table, and extending longitudinally of the center thereof, with its rear edge termi- 5 9 nating flush with the rear edge of the table A table 18 for feeding the blanks is pro- 18; the former being supported by an arm 40 projecting upwardly from one side of the feed table 18 and overhanging the working bed thereof.

As the blank is ositioned under the former it is engaged rom the underside by a reciprocating folding arm 41 substantially U-shaped in cross section, and forced around the former 39 until it assumes a semi-cylindrical or substantially U-shaped structure, as disclosed in Figs. 6, 7 and 8 of the drawings. The folding arm 41 is formed with a substantially U-shaped upper surface, the concavity of which is slightly larger than the diameter of the former 39 to permit the reception of the blank between the surfaces thereof, and is mounted to reciprocate through a suitable opening 39 in the feed table 18, directly below the former 1 39; the folding arm in its movement being guided b suitable lugs or guides 42, which project aterally from each side of 'said arm, and extend downwardly from the under surface thereof, the lugs being slidably mounted in vertical tracks or grooves 43 formed in brackets 44 secured-to the unders'ide of the feed table at each side of the link between its pivotal point and the oval opening therein and operated in a cam groove 49 in a wheel 50 keyed to rotate with the shaft 4.

After the sides of the blank are curved upwardly, the whole forming a semi-cylindrical or substantially U-shaped structure and the curved foldin arm 41 is in its elevated position part y surrounding the former 39, the blank is engaged in its front edges and pushed rearwardly 01f of the former 39 onto a mandrel 51, mounted 011 the forward face of the supporting wheel 10, by a pair of oppositely disposed lugs 52 secured to the rear end of an oblong cylindrical plunger 53, mounted to reciprocate in a suitable opening extending longitudinally through the center of the former 39, the lugs 52 projecting through longitudinally extending slots 54 arranged one in either side of the former 39, the lugs also projecting into horizontally disposed guide ways 55 arranged one in either side of the inner surface of the foldin arm 41 adjacent the up per edges thereof A reciprocating movement is imparted to the plunger 53 through a rack 56 formed longitudinally of the upper surface thereof, the rack intermeshing with a segment 57 secured to the inner end of a shaft 58 and projecting through a suit able cut out in thetupper surface of the former 39, the shaft being rotat-ably mounted in a housing 59 extending longitudinally of the upper edge of the arm 40, the outer end of the shaft carrying a segment 60 which intermeshes with a rack 62 formed in one face of a reciprocating arm 63, the arm reeeiving its movement through a lever 64 pivoted as at 65 to a suitable support 65', and carrying at its inner end a roller 66 which operates in a cam groove 67 of the disk 68 which is mounted to rotate with the shaft 4. The arm 63 is mounted in a suitable guide way 69 formed at the outer end of the arm 40 and is connected at its lower end to the outer end of the lever 64 by an adjustable link 70.

The timing and operation of the respective parts is such that as each blank is pushed rearwardly from the former, a forming mandrel is in position to receive the same.-

The mandrels 51 around which the containers are formed and the clamping arms associated therewith are sup orted in spaced relation to each other on t e forward face of the supporting wheel 10 adjacent the peripheral edge thereof; and each mandrel and its associated parts being the same, it is not thought necessary to describe each one separately, but a description of one is thought will suflice. 7

Each mandrel 51 is in the form of a hollow cylinder closed at its outer end as at 51' and tapering as the frustum of a cone and Figs. 12, 15 and 16 of the drawings.

is mounted at right angles to the front face of the wheel 10 with its tapered end outwardly and the enlarged end secured in any suitable manner to the face of the supporting wheel 10. In the outer end of the mandrel is formed a circular depression '72, which provides a seatfor a disk shaped expelling plunger head 73, which is provided with a supporting shaft 7 4 in which is formed a longitudinal bore '76 the shaft 74 extending longitudinally of the center of the mandrel, through a suitable opening in the wheel and projects a short distance in the rear thereof, the plunger head being normally retained in its seat by the action of a spring 75 coiled around the rear thereof.

Mounted on the supporting wheel 10 in spaced relation below the mandrel 51 and arranged angularly thereto is a supporting bracket 7 6', the outer end of which is curved upwardly in spaced relation to the supporting wheel 10 and is provided with spaced bores which form a bearing for the inner ends of rotatably mounted stub shafts 77 and 78, which extend respectively through corresponding bores in the lower ends of supporting lugs 79 and 80 extending respectively from the lower edges of semi-cylindrical clamping arms 81 and 82, adjacent the forward ends thereof, as disclosednin 1e clampin arms 81 and 82 extend longitudinally o the mandrel, one on either side thereof, and the curved inner faces thereof are of substantially the same curvature as the contour of the mandrel 51, and when said arms 81 and 82 are clamped around the mandrel, in a hereinafter described manner, the upper edges thereof are in substantially meeting relation and the lower edges are spaced apart, the space therebetween being filledby a lower clamping jaw 83, hinged at its rear end as at 84 to the sup orting wheel 10 and operated in a hereina ter described manner. The side clamping arms 81 and and 82 and the bottom clampin jaw 83 project slightly beyond the en of the mandrel 51, as in Figs. 11 and 12 of the drawings] The lower clamping jaw 83 is forced against the mandrel 51 by the action of a shaft 85, extending through the suppor ing wheel 10 and carryin at its forward end a. cam 86 adapted to' e rotated by the shaft into engagement with an outwardly projecting lug 87 on the under surface of the jaw 83. he shaft carries on its rear end a suitable arm 88 having an enlarged portion 89 at one end thereof, which, when the wheel 10 is rotated contacts with the upper end of a dog 90 pivotally mounted as at 91 to a suitable support 92 projecting from the upper end of the support 3, the dog adapted to be actuated by a cam block 93 mounted on the shaft ,4 and which con- I arm 81 will be e xmmoe tacts with an antifriction roller 94 on the lower end of the dog.

Loosely surrounding the shaft 85 between the cam 86 and the arm 88 and rotatably mounted in an opening in the wheel 10 is a sleeve 95 the forward end of which is se cured in a bore in the supporting lug 96 projectin from the lower edge of the clamping arm 81 near the inner end thereof, and to the rear of said sleeve is secured a toothed segment 97 which intermeshes with a cor responding segment 98 on the inner end of a shaft 99 positioned adjacent the sleeve 95 anu rotatably mounted in the wheel 10, the torward and of said shaft 99 being mounted in a supporting lug projecting from the lower edge of the clamping arm 82 near the inner end thereof. An arm 10]; extends laterally from a portion of the edge of the segment 98 and is pivotally connected as at 102 to one end of a link 103, the other end of said link being pivotally connected as at 104 to the end of an arm 105 pro'ecting from a 1 hub 106 pivotally mounted 1:; out a stud 10? secured to the-wheel 10. At the end of the link 103-adjacent the pivot point 104 is formed a finger 108, which, when the parts are operatedin a hereinafter described manner and the arms 81 and 82 are closed, is adapted'to contact with a flattened seat 109 rovide a lock for the arms as disclosedin igs. 13 and 14 of the drawings. i p

The segments 97 and 98 are so arranged that when the clamping arms are closed mandrel, the arm 82 will close first, forcin that portion of the blank carrying the a hesive around the mandrel with the adhesive side upwardly, and then the clamping d, bringing the other blank over, and after drawtightly around the mandrel against the adhesive n securing the two portion of the ing the blank forcing the top edge on-the under edge, a edges together. I v

The machine is timed to operate in such a manner that after the blank in its substantially U-shape form is fedto the mandrel and the plunger 53 is drawn back to the position in Fig. 5, the wheel 10 will be rotated by the elements of the Geneva gearing coming into operation, and while the wheel is in its. movement, the arm 88 in its path of movement will be engaged by the dog 90 and the cam 89 associated with said arm through the shaft 85, will be operated, forcing the lower clamping jaw 83 upwardly and clamping the blank to the mandrel. When this operation is completed the Geneva. gearin will be in its inoperative relation and t e mandrel carrying the semiformed container blank will be at a p int f rest bef e b tt m pbelow the I 117, secured to j the lever being witha suitable idler roller 118 adapted to operate in a cam groove riphery of a cam wheel 120, keyed to rotate a with the shaft 4.

tacle are fed to the appl 'ng plun ,fomdd't' .wth fit around the blank as it is supported by the i r e 1 z e 1 a a .wardly inclined trough or chute,

plying station which inserts a bottom in the semiformed container and operates in the following manner :i*ecured to the feed table 18 at the opposite side thereof from the arm 40, is an upstanding bracket 110 provided at its top with an enlarged bore 111 through which reciprocates a suitable cylindrical plunger 112, to the outer end of which is rotatably mounted a plunger head 112, it being attached by a headed bolt 112 Extending circumferentially of the outer end of the rotatable plunger head 112' is a split ring 112 formed respectively with rectangular front and peripheral edges 112 and 112 and a beveled inner edge 112 which eontactswith a suitable bevel on the rotatably mounted head 112'. The ring 112 when in its normal position on the rotatable head is of the same diameter as the inside diameter of the flanges of the bottoms to be. applied; Extending from the rear of the plunger is an ad3ustable link 113 pivoted as at 114 to the upper end of a lever 115 extending upwardly through an'opening in the feed table and pivoted table 18 as at 116 to a bracket the underside of the table; provided at its lower end 119 cut in the pe- The bottoms to be app ied to the receper in a vace and a flanged periphery; through a downformed of parallel spaced angle rods 121 and 121, the

lower ends of which are supported by the ibracket 110, at right angles to the outer flat face of the plunger, and terminate short of the front of the enlarged bore 111 The bottoms are positioned in front of the plunger head by a air of fingers 122 and 123, pivoted respectively as at 124 and 125 to the upper and lower guides or memhere 121 and 121' of the chute,'the fingers being connected together by a transverse rod 126, the ends of which are pivoted to the fingers as at 127 and 128i Thefinger 123 is pivotally connected ata point in ad Vance of its pivotal point 125, by a rod 129, to the upper edge of an oblong adhesive containing receptacle 130, which is pivotally mounted at its rear end as at 131 to the bracket 110,. the front end of the recep tacle terminating below the finger 123.

Rotatably mounted in the adhesive receptacle near the forward end thereof, on a shaft 131 journaled in either side of the receptacle, is an adhesive applying disk 132 which is rotated by an endless drive chain 133, extending around a toothed drive heel 134: keyed to the shaft 4, and around a suitable toothed gear 135 carried by the shaft 131' exteriorly of the'receptacle.

The adhesive containing receptacle 131 is pivotally connected at its underside near the forward end thereof to an adjustable rod 136, the lower end of which is pivotally'connected to one end of a lever 137 pivotally supported as at 138 to a bracket on the standard 19, the opposite end of said lever being provided with an idler roller which contacts with, and is operated by the peripheral surface of a cam roller 139 keyed to rotate with the shaft 4 and positioned adjacent the toothed wheel 134. The chain 133 contacts with a stationary idler 140 rotatably mounted in the feed table 18 and with an idler 141 under suitable spring tension, the idlers maintaining the-chain taut at all times; I

From the above descri tion it will be readily seen that when e cam member on the roller 139 contacts with the lever 137, the adhesive applying disk- 132, which is rotated in the direction of the arrow-Fig. 9w,ill be forced against the. eri heral flange of the bottom, as it is carried y the forward end of the plunger head and retained between the fingers 122 and 123, and will rotate the bottom and the rotary plunger head 112', coating the entire circumference of I the flange with adhesive, at which time the cam member on I the roller 139 will have passed its point of contact with the lever 137, permittin the forward end of the adhesive receptac e 130 to drop, which being connected by the rods 129 and 126 with the fingers 122 and 123 will cause the same to open outwardly away from the periphery of the bottom, and permit the plunger 112 to move therebetween and to alpply the bottom to the semi-formed receptac e.

A short interval before the bottom is a plied to the receptacle in the above d e pivot 104, connectin the arm 105 and whic scribed manner, t

the link 103 and projects slightly outwardly from the link will be engaged by a spring finger 142 carried at the upper end of the arm 143 operated in a hereinafter described manner, and forced upwardl partly closing the clampng arms 81 and 82 around the blank forming the same into a substantially cylindrical body but not forcing the upper edges of the arms 81- and 82 intomeeting relation or the finger 108 against the seat 109. The

lower end of the arm 143 is pivoted as at 144 to a supporting rod 145 whichis mounted to reciprocate vertically in a guide way 146 formed at standard 3, the supportin rod 145 being provided at its lower end with an idler roller 147 which contacts with the peripheraledge of a cam 148 keyed to rotate with the shaft 4. To permit the arm 143 t after the len arm 88, and

the extreme upper end of the follow the ivotal point 104a short distance fi hger 142 has engaged the same and to limit the lateral movement of said arm, the arm 143 is provided midway of its hwith an arcuate slot 149 through whlch projects a stud 150, carried by the upapr end of the supporting rod 145. a hen the clamping arms 81 and 82 are part1 closed around the blank, as previously state the cam 148 is in a position of its rotation with the edge A thereof contacting with the roller 147, sition the bottom is forced in the substantially c lindrical body by the timed actuation o the. lever 115 by the cam groove 119. The peripheral edges of the bottom are forced against the sides of the contain'er by the *action of the split ring 112 as the flat face of the bottom contacts with the mandrel head 73. Afterthe bott0m is placed in the container the cam 148 in its movement of rotation will, through its associated parts clamp the arms 81 and 82 tightly around the blank and lock the finger 108 in its seat 109. The action of the clamping arms 81 and 82is such that asithey are closed around the blank the same is drawn ti htly around the'mandrel, the overlapped cf es thereof are clamped'one on the other an the bottom is tightly clamped in place.

The above operations take place successively as each mandrel is positioned before the blank feeding and bottom applying stations, and as the wheel 10 has about completed its revolution the s ring arms 151 and 152 carried by the upright 8 to engage respectively the projecting pivot 104 and an arm 89' projecting upwardly from the as the wheel 10 continues to revolve open the side clamping arms 81 and 82 and drop the lower jaw 83. The wheel 10 in its movement forces the shaft 74 into contact with the incline 153 of an ejector block 154, Sn ported on the member 8, the plunger head 73 of the shaft forclng the container lon 'tudinally of the mandrel, until the longitu inal bore 76 in the shaft alines with a compressed air blast 155, at which time the completely formed container will be blown from the mandrel. The air is compressed by a suitable pump 156 operated by the shaft 7 and forced into a receiver 157 which is connected through a suitable ipe 158 to the aperture 155, a rotary va ve 159 is mounted in the pipe 158 and is provided with an operating head formed of a plurality of outwardly projecting fingers 160 which are adapted to be engaged by outwardly projecting pins 161 arranged in spaced relation on the wheel 5.
